Methods and systems for automated coupon processing

ABSTRACT

A computer-implemented method for processing coupons in a point of sale terminal includes receiving electronic coupon data representing a machine-readable coupon code. The coupon code is associated with a coupon presented by a customer at a retail point of sale. The method further includes receiving electronic coupon validation data representing at least one valid coupon code and/or at least one fraudulent coupon code. The method further comprises determining whether the coupon is valid based on the coupon code and the valid coupon code(s) and/or the fraudulent coupon code(s), and identifying the coupon as accepted or invalid based on the determination of whether the coupon is valid.

BACKGROUND

Embodiments of the disclosure relate generally to data processing, and more particularly to methods and systems for automatically processing coupons in retail stores.

Coupons issued by vendors, manufacturers, retailers and others are often used by customers to save money by reducing the price paid for certain products and/or services at the point of sale. For example, when checking out, the customer may present a coupon to the retailer for one or more of the products being purchased. The retailer then reduces the receipt total by the redemption value of the coupon, provided that the coupon has not expired and any other conditions associated with redeeming the coupon have been met. If the coupon is issued by an entity other than the retailer itself, the retailer can recover the redemption value from the issuer of the coupon, often using a clearing house to perform this service. For example, the retailer may send the redeemed coupon to the clearing house, which in turn pays the retailer the redemption amount and separately recovers the payment from the issuer of the coupon.

Coupons are most commonly issued in paper form, and are manually handled and processed by the retailer at the point of sale, as well as in a back office, for verification, accounting, auditing and other purposes. For example, some paper coupons may need to be visually verified and/or manually keyed in by a store clerk, tasks that are not always done consistently or reliably. In addition to verifying expiration dates and redemption conditions, some retailers are also vigilant in identifying fraudulent or counterfeit coupons at the point of sale, because if a coupon is discovered to be fraudulent or counterfeit after the sales transaction is complete, the retailer may have no recourse against the customer. Also, paper coupons may be manually sorted, counted, verified and/or keyed into an accounting register in the back office, which can introduce errors, discrepancies, and other inefficiencies. Since some large retailers may process thousands or tens of thousands of paper coupons per day, processing inefficiencies can be compounded by the volume.

DETAILED DESCRIPTION

According to various embodiments, computer-implemented methods, computer-readable media and systems are disclosed for automatically processing coupons redeemed by customers in a retail store. Coupons tendered by a customer at a point of sale terminal can be automatically validated based on various conditions, including the expiration date of the coupon, whether one or more qualifying products have been purchased, and whether the coupon is valid or fraudulent.

FIG. 1 is a block diagram representing an exemplary overview of a computer-implemented process 100 for automatically processing coupons, according to an embodiment. A customer 110 who is shopping at a store operated by a retailer 120 presents one or more products, for example, products 102 a, 102 b and 102 c, for purchase at a point of sale terminal 122. The products 102 a, 102 b, 102 c may each have a corresponding barcode (e.g., a one- or two-dimensional barcode printed on the product packaging) for encoding a product code that uniquely identifies the product (e.g., a product stock keeping unit (SKU) number or manufacturer product code). The customer 110 also tenders, at the point of sale terminal 122, one or more coupons 104 a, 104 b and 104 c, for example, paper coupons that are machine-readable by the point of sale terminal 122, or electronic coupons electronically transferred to the point of sale terminal 122 from an application executing on a mobile computing device. While, in some embodiments, at least some automated processing of the coupons 104 a, 104 b, 104 c can occur at the point of sale terminal 122, the retailer 120 maintains a back office 124 for, among other things, performing further processing of the coupons 104 a, 104 b, 104 c tendered at the point of sale terminal 122 (e.g., for performing certain post-sales transaction activities).

The coupons 104 a, 104 b, 104 c include at least one barcode for encoding a coupon code representing the coupon, such as coupon type, manufacturer identification, redemption value and expiration date, among other types of information. For example, the barcodes may be encoded according to a standard such as Global Standard 1 (GS1) or Universal Product Code (UPC) Version A (UPC-A); other barcode formats may also be supported, including one-dimensional barcodes or two-dimensional barcodes (e.g., Quick Response Codes or QR codes). The point of sale terminal 122 includes a computerized register or terminal capable of reading the barcodes for the product 102 a, 102 b, 102 c and coupon 104 a, 104 b, 104 c (e.g., electronically scanning or transferring data), as will be understood by one of skill in the art. One example of a computerized point of sale terminal 122 is illustrated and described in connection with FIG. 4.

An electronic data path 106 represents the flow of barcode information from the products 102 a, 102 b, 102 c and the coupons 104 a, 104 b, 104 c to the point of sale terminal 122. It will be understood that in some embodiments, any number of products 102 a, 102 b, 102 c and/or coupons 104 a, 104 b, 104 c may be processed at the point of sale terminal 122. Although during some sales transactions there is at least one product 102 a, 102 b, 102 c purchased for each coupon 104 a, 104 b, 104 c tendered, in some other sales transactions, for example, multiple products may be purchased using a single coupon (e.g., buy one product, get another product free or at a discount with coupon) or multiple coupons may be redeemed for one or more products.

In some embodiments, the point of sale terminal 122 electronically transmits and receives data 126 (directly or indirectly) representing the products 102 a, 102 b, 102 c and coupons 104 a, 104 b, 104 c to and from the back office 124, a coupon validation service 130 and/or a clearing house 140 over one or more communication channels 128. The coupon validation service 130 provides the retailer 120 with electronic coupon validation data 132 including coupon codes representing fraudulent coupons (also referred to herein as fraudulent coupon codes) via a communication channel 134. The respective coupon codes of the tendered coupons 104 a, 104 b, 104 c can be automatically checked, at the point of sale, against the fraudulent coupon codes to determine whether any of the coupons 104 a, 104 b, 104 c are fraudulent or counterfeit. Fraudulent or counterfeit coupons can be identified as invalid, rejected by the retailer at the point of sale and returned to the customer 110. As used herein, the term identify or identified generally refers to a computer-implemented process of associating or assigning a qualifier or flag (e.g., valid, invalid, expired, fraudulent, etc.) electronically to the coupon. Such a qualifier may be stored in a memory or database operatively connected to the computer implementing the qualifier associating or assigning process (e.g., a point of sale terminal or back office computer system).

In some embodiments, the electronic coupon validation data 132 can further include coupon codes representing valid coupons (also referred to herein as valid coupon codes). The tendered coupons 104 a, 104 b, 104 c can be automatically checked, at the point of sale, against the valid coupon codes to determine whether any of the coupons 104 a, 104 b, 104 c are valid. Valid coupons can be identified as accepted, and accordingly accepted by the retailer at the point of sale provided that any other conditions for redemption are satisfied (e.g., matching product, un-expired coupon, etc.). For example, if a coupon 104 a, 104 b, 104 c is identified as accepted but does not meet one or more conditions for redemption (e.g., the products 102 a, 102 b, 102 c do not match any of the products for which the coupons 104 a, 104 b, 104 c are redeemable), the coupon 104 a, 104 b, 104 c should be returned to the customer 110 at the conclusion of the sales transaction or at any point before conclusion of the sales transaction.

The data 126 representing the coupon codes for coupons 104 a, 104 b, 104 c identified as accepted can be sent to the back office 124 of the retailer 120. The back office 124 includes one or more systems configured to further process the accepted coupons 104 a, 104 b, 104 c, for example, for performing accounting, auditing and other business functions. The back office 124 may be connected through a communication network 144 to a clearing house 140 for electronically transmitting processed coupon data 142 to the clearing house 140.

FIGS. 2A and 2B depict a flow diagram of an exemplary computer-implemented process 200 for automatically processing a coupon, according to an embodiment. Referring to FIG. 2A, process 200 begins at step 202. At step 204, coupon data for a coupon being redeemed by a customer is received at a point of sale. For example, the step of receiving the coupon data 204 may occur in response to scanning a coupon barcode at the point of sale (step 206) using a terminal configured to optically scan barcodes printed on the paper coupons 104 a, 104 b, 104 c. Scanning the barcode is one exemplary technique for entering coupon data associated with the coupon into the point of sale. It will be understood that other techniques for entering the coupon data may be used, such as manually keying or typing a barcode number printed on the coupon into the point of sale using a keyboard or other data entry device, or electronically processing an image of an electronic coupon transferred from a mobile computing device.

At step 208, coupon validation data is received at the point of sale. As described above, the coupon validation data may be provided by a coupon validation service 130 and can include valid coupon codes and/or fraudulent coupon codes for checking against the redeemed coupons 104 a, 104 b, 104 c. Step 208 may occur before, after, or concurrently to steps 204 and/or 206. For example, the coupon validation data may be received at the point of sale once at the beginning of each day, at the beginning of the sales transaction, or at other intervals or frequencies for keeping the coupon validation data current and available at the point of sale.

At step 210, the coupon data is checked to determine whether the coupon has expired (i.e., whether the current date is later than the coupon expiration date). Depending on the type of barcode on the coupon, the coupon data may not contain the expiration data (e.g., UPC-A barcodes may not contain the expiration date, but GS-1 barcodes may contain the expiration date.) If the coupon data contains the expiration date and the coupon is expired, the coupon is identified as invalid at step 212. If the coupon data does not contain the expiration date, the expiration date printed on the face of the coupon may be checked manually by a clerk at the point of sale.

If the coupon is not expired, at step 214, the coupon data is checked to determine whether the coupon is fraudulent. One or more pieces of information encoded in the barcode, such as the coupon type, manufacturer identification, family code and/or value code, can be checked against the coupon validation data to determine whether the coupon is fraudulent. For example, the coupon validation data may contain fraudulent values or coupon codes corresponding to one or more of the pieces of information encoded in the barcode. The fraudulent values or coupon codes may be determined by the coupon validation service or the retailer and included in the coupon validation data. If the coupon data for the redeemed coupon 104 a, 104 b, 104 c matches one or more of the fraudulent values or coupon codes, the coupon is identified as invalid at step 212. In some embodiments, other information or combinations of information in the coupon data can also be used to determine whether the coupon is fraudulent. For example, coupons that have correct coupon types, manufacturer identifications, family codes and/or value codes, but incorrect expiration dates, may be fraudulent and accordingly identified as invalid.

If the coupon is not fraudulent, at step 216, the coupon data is checked to determine whether the coupon is valid. One or more pieces of information encoded in the barcode, such as the coupon type, manufacturer identification, family code and/or value code, can be checked against the coupon validation data to determine whether the coupon is valid. For example, the coupon validation data may contain values corresponding to one or more of the pieces of information encoded in the barcode which were determined to be valid by the coupon validation service or the retailer. If the coupon data for the redeemed coupon 104 a, 104 b, 104 c matches one or more of the valid values, the coupon is identified as accepted at step 218, otherwise, the coupon is identified as invalid at step 212.

In some embodiments, step 214 or step 216 may not be performed in process 200. For example, if a redeemed coupon 104 a, 104 b, 104 c is not expired and not fraudulent, the coupon may be identified as accepted at step 218, bypassing step 216. In another example, if a redeemed coupon 104 a, 104 b, 104 c is valid and not expired, the coupon may be identified as accepted at step 218, bypassing step 214.

Referring to FIG. 2B, in some embodiments, if the coupon is identified as invalid, at step 220, a message can be displayed at the point of sale indicating to the clerk and/or customer that the coupon is rejected. If the coupon is identified as valid, at step 222, a message can be displayed at the point of sale indicating to the clerk and/or customer that the coupon is accepted.

As discussed above, some coupons can only be redeemed in conjunction with the purchase of one or more products. At step 226, product data for a product being purchased by a customer is received at a point of sale. For example, the step of receiving the product data 226 may occur in response to scanning a product barcode at the point of sale (step 224) using the terminal configured to optically scan barcodes printed on the products 102 a, 102 b, 102 c. Scanning the barcode is one exemplary technique for entering product data associated with the product into the point of sale. It will be understood that other techniques for entering the product data may also be used, such as manually keying or typing a barcode number printed on the product packaging into the point of sale using a keyboard or other data entry device.

Products purchased by the customer for which coupons may be redeemed are referred to as qualified products. For example, if the customer tenders a coupon for Brand A detergent, 28 ounces or larger, and purchases Brand A detergent—32 ounces, the 32-ounce Brand A detergent product is a qualified product because it satisfies the coupon redemption conditions (i.e., correct brand, product and size). By contrast, for example, if the customer purchases Brand A detergent—21 ounces, the 21-ounce Brand A detergent product is not a qualified product because it does not satisfy the coupon redemption conditions (i.e., correct brand and product, but incorrect size). In some instances, coupon redemption conditions may require more than one qualified product to be purchased. For example, if the customer tenders a coupon for “buy-one-get-one” Brand A detergent, the customer must purchase (or present at the point of sale) at least two Brand A detergent products to qualify under the coupon redemption conditions.

At step 228, the product corresponding to the product data is checked against the coupon data to determine whether the product is a qualified product. If the product (or products, if more than one product must be purchased under the coupon redemption conditions) is a qualified product, a receipt total is reduced by the coupon redemption value at step 232. For example, if the coupon redemption value is 50 cents, the receipt total is reduced by 50 cents. In some embodiments, the coupon redemption value is automatically calculated based on the coupon data (e.g., the redemption value is encoded into the coupon barcode).

At step 234, redemption data for each redeemed coupon is electronically transmitted from the point of sale to the clearing house 140 (e.g., via the back office 124). The redemption data includes the coupon redemption value for the redeemed coupon. The redemption data may be used, for example, by the retailer to recover the coupon redemption value from the issuer of the coupon (e.g., the manufacturer or distributor of the qualified product) via the clearing house. Process 200 ends at step 230. In some embodiments, process 200 can be repeated one or more times for each coupon tendered by the customer at the point of sale. In some embodiments, step 234 is performed subsequent to completion of the sales transaction, that is, after the customer has tendered all of the coupons he or she wishes to redeem.

FIG. 3 depicts examples of various coupon barcodes that can be used in conjunction with automatically processing coupons in accordance with some embodiments, including the process 200 of FIGS. 2A and 2B. One type of barcode is called a UPC-A barcode 310, and another type of barcode is called a GS-1 barcode 320. The UPC-A barcode 310 and GS-1 barcode 320 are each barcodes in which certain information may be encoded, such as the coupon type, the manufacturer identification, a family code and a value code. Generally, the GS-1 barcode 320 includes more information than the UPC-A barcode 310. Some coupons may have only one barcode, while others may have multiple different barcodes, any or all of which may be used in conjunction with exemplary embodiments. Chart 330 lists the various types of information that can be encoded in the UPC-A barcode 310 and/or GS-1 barcode 320 by reference to the “#” numbers. For example, the value “0035000” indicated by reference #3 in the exemplary barcodes 310 and 320 of FIG. 3 is the manufacturer ID for the coupon bearing either or both of the barcodes.
